Soundgarden will be celebrating the 20th anniversary of their 1994 album, 'Superunknown' by reissuing the record in two deluxe versions.
The first deluxe edition will be a 2-disc set featuring the remastered album and a second disc consisting of demos, rehearsals, B-sides and more. The other deluxe edition (The Super Deluxe Edition) will be a 5-disc set featuring the remastered album, additional demos, rehearsals and B-sides and a fifth disc of the album mixed in Blu-ray Audio 5.1 Surround Sound—all packaged in a hardbound book with a lenticular cover, liner notes by David Fricke and newly imagined album art.
A 2-LP gatefold of the original 16 vinyl tracks, remeastered on 200-gram vinyl in a gatefold jacket, will also be released.
In addition, and to help celebrate record store day, the Superunknown singles and associated B-sides with newly interpreted artwork sleeves will be reissued on Record Store Day, April 19th, as a set of five limited edition 10" vinyl records.
